A medical condition involving a bad or distorted sense of taste, such as tasting something unpleasant when it should taste normal.
From Greek kakos (bad) and geusia (taste), with the medical suffix -ia. It's a specialized term for taste disorders that cause bad or perverted taste sensations.
COVID-19 made 'cacogeusia' a household word when people reported foods tasting like metal or soap—it's the medical name for 'taste perversion' during illness.
